Patent number: 7820950Abstract: The invention relates to a pressure-sensitive supporting material, which can be (intrinsically) heated by an inner heat source, and to the use thereof. The heatable supporting material is characterized in that the supporting material comprises a pressure-sensitive adhesive layer inside of which heat is generated. The pressure-sensitive adhesive layer is a pressure-sensitive adhesive compound, which can be heated by electric current, induction, a chemical reaction or by a physical phase transition. The heatable supporting material has a high heating capacity and is suited for producing pressure-sensitive tapes for adhering heatable mirrors.Type: GrantFiled: February 18, 2004Date of Patent: October 26, 2010Assignee: tesa SEInventors: Klaus Keite-Telgenbüscher, Stephan Zöllner, Marco Kupsky, German Patino, Olaf Gōrbig
